ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI MECHANICAL ADVERTISING DEVICE Application filed October 9, 1930. Serial No. 487,528. 1

This invention relates to a mechanical advertising device.

The object of my invention is to produce ai r currents by an electrically driven blower and to cause said air to be rotated rapidly and discharge same from a nozzle, so that said air currents will act on a small rubber balloon, inflated with air, in such a manner as to support and hold said balloon in suspension and cause same to rapidly rotate.

My invention is particularly useful as an advertising medium in demonstrating the size,

location and rotation ofan oil flame from it certain type of oil burner-said invention R being used in the show rooms of many oil burner dealers throughout the United States to attract the attention of pedestrians, a spe-' cific instance of which is the Potomac Electric Company, of lVashington, D. O.

In the accompanying drawings, Figure 1 is a plan view of my invention, shown partly in sectionthe small air inflated balloon being shown in the position it takes when the air blower is in operation.

Figure 2 is an end view of the air receiver casting, which receives air from the blower and causes said air to rapidly rotate due to the fact that one end of said air receiver is in the form of an involute curve.

Referring now to the drawings, the numeral 1 indicates an electric motor which opcrates a blower wheel 2. The numeral 3 is a housing in which the wheel 2 operates, and which also supports the motor 1. The numeral 4 indicates a pipe for conducting the air from the housing 3 to an air receiver lA, said air receiver being in the form of an involut-e curve, as shown in Figure 2, so as to cause the air currents to rapidly rotate. The numeral 5 indicates a round extension projecting from the air receiver and being formed with a cone-like air nozzle 6. The numeral 7 indicates a tube which is supported by the air receiver 4-A, said tube 7' terminating near the end of the air nozzle 6, and acting as a support to a conical member 8, which member 8 is secured to the tube 7 by three or more small screws 9. Thenumeral 10 indicates a small rubber balloon, which is inflated with air.

In the operation of this device, I have found that when the electric motor 1 is in operation so as to cause the blower wheel 2 to force air into the air receiver 4A, said air will rapidly rotate in the chamber 5 and will emer e from the air nozzle 6 and conical member 8 in a rapidly rotatmg air stream, which has a vacuum near the central opening. 1 have found that by placing a small air inflated toy balloon in the position shown in Figure 1, that the vacuum created as above described will cause the balloon to be held in suspension as shown in Figure 1, and that zontally, from the nozzle orifice, the air filled balloon will be supported and rotated by said air stream.

2. In an advertising device, an air nozzle, an air filled balloon arranged'to cooperate with said nozzle, means for producing and rapidly rotating a body of air and ejecting said air from the nozzle orifice in a substantially, horizontal direction, a cone-shaped member, slidably arranged. within the air .n-ozzle near sald nozzle or1fice so that when a rotating body of air is ejected, substantially horizontally, from the nozzle orifice, the air filled balloon will be supported and rotated by said air stream.
